Half Column Shaft
Polure half column shaft provides classical wall-mounted architectural grandeur for interior feature walls, entryways, and facade designs. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this semi-circular decorative column shaft delivers wood-like mechanical durability while remaining lightweight to prevent wall strain. Featuring a closed-cell structure with water absorption under 1%, it will not rot, mold, swell, or deteriorate across temperatures from -100 °C / +80 °C. Rated Class B2 for self-extinguishing flame resistance, each piece is pre-coated with factory white acrylic technical primer. Designed as a hollow decorative cover for wall applications or wrapping around existing semi-circular supports. Installation requires continuous polyurethane assembly adhesive on wall contact edges, paired with mechanical countersunk screws. Fill joints and screw holes with acrylic putty, sand smooth with 180-220 grit paper, and finish with quality paint.
